鉴于以下JSON和模式，actor.mbox，actor.member [0] .objectType和actor.member [0] .mbox都应该失败。他们不。我的架构中肯定有问题。我认为我已将其范围缩小到与IdGroup定义有关的内容，但我找不到问题。任何json架构大师都看到明显的错误吗？

答案 0 :(得分：1)
if/then/else并不像您期望的那样工作。
在架构定义中，allOfAgentGroup有一个oneOf部分。
让我们看看它本身。
在应该失败的示例数据中，让我们自己也使用“ actor”对象。
模式：
{
"oneOf": [
{
"if": {
"properties": {
"objectType": {
"const": "Agent"
}
}
},
"then": false
}
},
false
]
}
实例数据：
{
"objectType": "Group",
"name": "Group Identified",
"mbox": "http://should.fail.com",
"member": [
{
"objectType": "Agent_shouldfail",
"name": "xAPI mbox",
"mbox": "mailto:shouldfail"
}
]
}
我们知道您希望oneOf数组中的第二部分验证失败。
为了进行调试和演示，我们假设它确实失败了，然后将其更改为false（这是一个有效的“ JSON Schema”，总是导致该分支上的验证失败）。
现在，鉴于上述架构和实例，您将希望JSON实例数据无法通过验证，对吗？ 事实并非如此，并且验证通过了。
请记住，每个JSON Schema关键字都会为您的验证需求添加约束。
让我们看看if和then的实际用途。
if
此关键字的子模式的验证结果没有直接的 对整体验证结果的影响。而是控制哪个 评估“ then”或“ else”关键字。
已针对该关键字的子模式成功验证的实例 还必须针对“ then”关键字的子模式值有效， 如果有的话。
http://json-schema.org/latest/json-schema-validation.html#rfc.section.6.6
好的，因此，如果if的模式成功验证，则将应用then中的模式。
实例数据无法通过if条件验证，因此...未应用then中的模式，最终得到的是有效的“空模式”，这意味着{ {1}}。这导致您oneOf/0断言验证成功，因为oneOf通过而oneOf/0失败。
要解决此问题，您需要将oneOf/1添加到包含"then": false和if的对象中，以防止{{1 }}条件不满足。
